Georgian Royal Coat of Arms

Central Panel: The Tunic of Out Saviour Jesus Christ
According to a Georgian tradition, the tunic (chiton) was recovered after Jesus Christ's crucifixion and brought to Mtskheta, ancient capital of Georgia.

Top Left Panel: The Sling with which David killed Goliath and David's harp, symbolizing Bagration's claim to a Biblical descent from King David of Israel.

Top Right Panel: The Royal Orb and Crossed Swords

Bottom Left Panel: The Scales of Justice

In some versions )see left image), there is an additional panel: St. George killing the dragon.
St. George is the patron saint of Georgia, although "Georgian" St. George has many archaic features that he "inherited" from local pagan deities.
